## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-605R, A300 B4-622R, and A300 F4-605R airplanes. This AD requires repetitive high frequency eddy current (HFEC) or rototest inspections to detect cracking in the area surrounding the frame feet attachment holes between fuselage frames (FR) 41 and FR46; installation of new fasteners for certain airplanes; and follow-on corrective actions, if necessary. This AD is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent cracking of the center section of the fuselage, which could result in rupture of the frame foot and reduced structural integrity of the airplane.
